20 Claims.

(Granted under the act of March 3,1883. as amended April so, 1928; 370 0. G. 757) The invention described herein may be manufactured and used by or for the Government for governmental purposes, without the payment to us of anyroyalty thereon.

This invention relates to printing telegraph machines. and more particularly to functional translators or selectors and function performing devices for such machines.

The invention supplements our previous Patent No. 2,128,242, dated Aug. 30, 1938, and application Serial No. 102,178, filed September 23, 1936, which disclose an exactly synchronized printing telegraph system, and new features in printing telegraph mechanisms. The present invention comprises functional translator mechanisms and function performing devices used with themechanisms previously disclosed.

One of the main objects of the invention is to provide a printing telegraph machine functional translator or selector.

Another main object of the invention is to provide means responsive to electrical signalling for the selection of such printing telegraph machine functions as line feed, carriage return, and figures and letters shift.

Another main object of the invention is to provide means for the presentation of the selected functional members to power driven cam operation of the selected functions.

Another main object of the invention is to lock out the automatic carriage step forward mechanismwhenever a function is selected.

Another main object of the invention is to provide a functional translator or selector operative in conjunction with a permutation disk or code disk translator.

Another main object of the invention is to employ the movement of pertinent stunt bars or selector bars of a permutation disk or code disk translator to operate cocked triggers releasing function selectors, the power for the performance of the selected function being derived from a prime mover and including power reset and spacing mechanism disengagement features.

Another main object of the invention is to associate all function selectors in one combined group coordinated to operate upon a common universal bar, the universal bar also acting to reset any or all selectors. This feature alone is very valuable in the art because all previous mechanisms scatter the function performing devices at random about the machine. I

Another main object is to provide a functional selector as a complete and replaceable unit.

Other important objects will become apparent to those skilled in the art as the description pro-' ceeds.

The principles of the invention are illustrated in the embodiment depicted in the accompanying drawings, in which: I

In Fig. 1, we represent schematically our printing telegraph machine terminated at the ground connection 2 and the line terminal L. The motor 223 drives shaft I35 continuously through bevel gears 224 and I34. The gang cam group I30 is at rest because the driven positive clutch member I3I is held out of engagement with the driving clutch member I32 by the clutch arm I31 against the tension of spring I 33. Bevel gear 225, likewise in continuous rotation, drives gear I 66 through gears 226 and 221. The vertical shaft 2II is pinned to gear I 66 and is also in continuous rotation.

The vertical shaft 2II transmits drive to two friction clutches; one for the type wheel I52 at 206 and 261; and the other for the rotor of the shuttle selector I90, and through gear 228, the reed escapement and distribution shaft I65. The type wheel I52 is rotated from selected position to selected position; the stoppage of the type wheel at a selected position being caused by the interference of the pertinent stunt bar 2| 4, se-

lected by the alignment of slots in the translator code disks 2E5, in the path of the type Wheel stop member 2I2. The rotation of the shuttle selector I90 and of the reed escapement and distribution shaft I65 depends upon the position of the reed I12, and its escapement yoke I15, with respect to the escapement pins I14a to I14 inclusive mounted on the escapement hub I14 which is pinned to shaft I65.

The reed I12 is clamped at I19 and, upon being released, vibrates between the dotted positions I'I2a and I121) in six half cycles of vibration from start to stop. The normal or start-stop position of the read is at I'I2a under the latch III of the start-stop magnet 62.

The distributor 51 performs an automatic stop, function in a local circuit on the reed start-stop magnet 92, switching the magnet from the control of the line relay 48 direct to battery at segment 69a and switching back to line relay 48 control at segment 98 during one revolution of distributor arm 58. The transmitting distributor 49, in the progression by reed escapement of the distributor arm 59 from segment 56 to segments 5|, 52, 53, 54, 55 and return to segment 56, performs the function of step by step connection of the keyboard transmitting contacts I'I, I8, I9, 29 and 2| to the line I through line relay 48.

The cams 243 and 29,4 on the extremity of shaft I95 in conjunction with the cam levers or arms 245 and 258, the link 253, the release-restore bar 258, and the keyboard universal bar 24 operating latch 259, perform the functions of release and restore of the transmitting contact levers I2, I3, I4, I5 and I6, the contact lever 22 being the startstop feature which is normally held closed with respect to contact 23. The keys of the keyboard, of which one is shown as 32, operate to rock the code bars 25, 26, 21, 28 and 29 into marking or spacing positions in accordance with the permutations of the five equal unit code. The code bars in turn set the contact pawls 291, 298,269, 210 and 2'II, in marking or spacing positions with respect to contact levers I2, I3, I4, I5 and I8. Upon the release of bar 256 the contact levers under spring tension will either make contact, or not make contact, with the transmitting contacts IT, IS, I9, 29 and 2 I, dependent upon whether or not a contact pawl is interposed in spacing position as shown in the figure.

The shuttle selector rotor I99 is in step-by-step relationship with the transmitting distributor arm 59 under the joint escapement action of reed II2 driving escapement yoke II5 to permit the progression of escapement pins IMa to NM, inclusive. The shuttle selector rotor I98 and stator I89 is shown in detail in Figure 4, and in Figures 2 and 3 in relationship with the selecting magnet 65 and its armature 65. The shuttle selector track switch and armature is shown in Figure 5. Suffice it to say that in one revolution of the rotor I99 the shuttle selectors I99a to I98e are assigned to either the marking track I89a or the spacing track I891) dependent upon whether the armature 56 is in marking or spacing position at the instant each particular shuttle selector passes the armature at the track switch.

The code disk translator is shown in a detailed cross-sectional view in Fig. 2 at 2I3, the permutation disks or slotted code disks being 2 I 5 and the transverse members or stunt bars at 2M. The particular stunt bar at 2M is shown in selected position effecting the stoppage of type wheel I52 at the stop member 2I2.

The selector transfer assembly which transfers the established selection from the shuttle selec tor to operate upon the code disk translator at the proper time is the transfer frame I92 (Fig. 2) carrying the five transfer cams I920 to I92e. See also Fig. 6. Upon downward movement of the transfer assembly, the transfer cams I92a to I926,

are set in marking or spacing positions. as deter-.

mined by the shuttle selectors I980. to I 98c, and the transfer cams operate upon the push-pull bars 2I6a to 2I9e, to rotate the individual code disks toward marking or spacing positions. Upon the return to normal or upward movement of the transfer assembly the operation is completed; that is, the code disk rotation into marking or spacing positions is completed. The V members shown on the bottom of the translator housing 2 I3 directly above the transfer cams serve to cam the push-pull bars into the completed movement. The selector transfer assembly in the down and up movement described performs another function; that is, of clearing or resetting the translator stunt bars 2 I4 to a normal position in the downward movement, and in releasing all stunt bars for the selection of one stunt bar in the upward movement, by means of the reset disk formed at the top of the transfer frame I92 act-- ing upon the stunt bar extensions about pivot 2I8. The transfer shift yoke arm is I93 (see Fig. 3) with pivot at I9I.

Now in this invention we are mainly concerned in describing our function selecting mechanisms and function performing devices from the initial selection at a given stunt bar in the code disk translator through the selection and performance of a given machine function, and the interaction of our previously described mechanisms.

The relationship of the functional translator with the code disk translator is shown in plan view in Fig. 7, and a detailed view of the trigger action of a stunt bar of the code disk translator upon the functional translator is shown in Fig. 8. The pertinent members are also shown in a side elevation view in Fig. 3. In Fig. '7 the function selecting stunt bars of the code disk translator are designated 2I4a, 2M1), 2M0, and 2I4d, which are assigned respectively to line feed, carriage return, letters shift and figures shift. In Fig. 8 the disposition of details is shown before a selection has been effected and in Fig. 7 after a selection has been effected.

In Fig. 8, 2 Md is the figures shif-t stunt bar, 219 is the trigger latch, and 283 is the action bar. The trigger latch is held cooked in normal position by a compression spring. In this position the latch holds the action bar 283 in normal position. The code disks of the translator are 2I5 and the translator housing 2I3. Upon a proper I selective permutation of the code disks the stunt bar is drawn into an alignment of slots in the code disks, thereby thrusting the trigger latch 219 out from under the action bar 283 which moves down sharply under spring tension as shown in Figs. 3 and 7. Stunt bars 2I4a, 2 I 4b, and 2M0 operate in an identical manner upon trigger latches 216, 221 and 218, and the action bars 238, 28I and 282.

With reference to Figs. 3 and '7; 288, 289, 299 and 29I are connecting links between the action bars 289, 28I, 282 and 283, and the functional selectors 3I5, 3I6, SI! and MB of the functional translator. Hence it will be seen that the functional selectors operate from a normal position at the right to an off-normal position to the left. Operation of any one of the functional selectors throws a universal and reset bar 293 off-normal about pivot 292. The universal and reset bar 293 is equipped with an arm 294 which operates upon the carriage spacing lock-out lever 295;

i. e., operation of any functional selector locks out the automatic carriage spacing feature of the machine. Also the restore action of the universal and reset bar 293 upon the functional selectors, connecting links, action bars and trigger cam 229 and cam lever 296, and removes the lock from the automatic carriage spacing feature.

The line-feed functional selector 3I5 in opera- 1 tion to the left, under spring action, positions push rod 3I4 above the thrust lever 298. At the proper time the thrust lever 298 is raised under power drive through shaft I by means of the functional cam lever 291 and cam 320. Attention is invited at this time to the fact that the power for the performance of all functions is transmitted through this cam lever 291 and cam 320 each function being presented to the drive stroke by the functional translator selectors. The up stroke of the push rod 3M exerts a down thrust on the ratchet bar 322 through the lever 32l. It will be noted that the construction of the ratchet bar permits free movement of the carriage across the face of the type Wheel I52. The down stroke of the ratchet bar 322 and ratchet 3 24 rotates the ratchet Wheel attached to shaft I4I which carries the paper roller I38. The dog 325 serves to prevent back slip.

In every printing operation'the carriage is automatically spaced by the action of cam lever 232 upon arm 234 and ratchet 231 in engagement with rack 238, except when arm 234 is held normal and locked out by the carriage spacing lock-out lever 295 as the result of function selection. I Each spacing operation builds up tension in the carriage return spring I60.

The carriage return functional selector 3I6 in operation to the left, under spring action, positions push rod 3I9 above the thrust lever 298.

- Upward motion of the push rod 3I9 acts upon the finger 321, through arm 326 and a proper pivot, to disengage the holding dog and spacing ratchet 231 from the carriage rack 238, thus permitting the carriage to return to, the start of line position under action of spring I60.

The'lettersshift functional selector 3I1 or the figures shift functional selector 3I8 in operation to theleft under spring tension, positions a shift lever 300 to the left or right with respect to the pivot 300a. Reference is now made to Fig. 9. The shift lever 300 in turn moves a yoke 366 left or right. The yoke is connected to two legs 361 and 308 which are pivoted at 309 and 3I0 on the shift frame 3. The legs 301 and 398 present extensions to thrust levers 303 and 304.

Hence as to whether or not the extensions of the legs are engaged by the thrust levers is determined by the position of the shift lever 360 which in turn is established by the letter shift 1 functional selection 3" or the figure shift functional selector 3i8. The shift frame 3 is pivoted at 305 and is rocked into one of two positions upon the down stroke of the thrust levers. The shift frame sets the carriage 239 into letters or figures position, that is the paper roll I38 (Fig. 3) into letters or figures position with respect to the type wheel, by elevation or depression of the carriage about .240 by means of the connecting arm 3I2. The down stroke of the thrust levers 303 and 364 occurs at the proper time as transmitted by cam 320 (Fig. 3) through cam lever 291 and shaft 30I (Fig. 7). In Fig. 7 the selection is shown made for figures shift and in Fig. 9 the selected function of figures shift is shown performed.

Reference is made to Figs. 1, 3, l0, and 11. The gang cam group assembled upon the tubular sleeve I30 is normally at rest but, upon the completion of the processes of transmission, re-

ception, and selection, is permitted to rotate one complete revolution by the timed engagement of the driven clutch member I3I with the driving clutch member I32 which is connected by shaft I35, gear I34, and gear 224 to the drive of motor 223 (Fig. 1). Cam 23I operates upon the ribbon feed mechanism, the details of which are not shown herein. Cam I29 operates upon the devices which transfer a selection from the shuttle selector to the code disk translator and release and reset the stunt bars thereof. Cam 230 operates upon the printing and automatic carriage spacing devices. Cam 320 transmits power at the proper time for the machine operations of line feed, carriage return, letters shift, and figures shift, upon the pertinent selection of any one of these functions by the functional translator. Cam 229 removes the carriage space lockout, and restores the selectors of the functional translator to normal, recocking the selected trigger latch in normal position. A graphical representation of the relation of the cams through one revolution of the group is shown in Fig. 11. Now let us consider a typical example of operation throughout from the transmission of a desired function, by keyboard operation at one station, to the performance of this function at the local and distant station. Let us assume it is desired to transmit, and effect the performance of, the figures shift function. In our signalling code the figures shift function is assigned as I marking, 2 marking, 3 spacing, 4 marking and 5 marking.- Reference is made to Fig. 1 representinga local machine connected by line and ground return to an identical distant machine. In the normal state the motor 223 is operating and shafts I and 2 are in continuous rotation with the type wheel at rest, its friction clutch slipping, and the shuttle selector rotor I90 and escapement shaft I65 at rest with friction clutch slipping, the reed I12 being latched in position H211 and hence holding shaft I65 from rotation by the'engagement of the escapement yoke I15a under escapement pin I14a. The line circuit is closed in normal state at the start-stop contacts 22 and 23, the circuit being from battery 3, wire 4, contact 23, contact lever 22 closed, wire II, wire I0, line relay 48, line wire I, through an identical circuit at distant station including poled battery and return at ground 2 to battery 3. The line relaycontacts hold the selector magnet 65 in'marking position in a local circuit, and also hold the reed magnet 62 energized in a parallel local circuit through distributor 51. The gang cam group I30 is at rest being disengaged from drive at clutch member I3 I.

The figures shift key 32 is now depressed setting up the code combination I, 2, 4, and 5 marking, and 3 spacing, of the code bars 25, 26, 21, 28, and 29, and the contact pawls 261, 268, 269, 210, and 21I, as shown in Fig. 1. The universal bar 24 is also operated which by the withdrawal of latch 260 releases the transmitting contact release-restore bar 256 to open the start-stop contact lever 22 from contact 23, and permit contact levers I2, I3, I5 and I6 to close with respect'to contacts I1, I8, 20 and 2I, the contact lever I4 being held open with respect to contact I9 by interference of pawl 269 in spacing position. I

The removal of contact lever 22 from contact 23 opened the line circuit releasing the line relay 48 andin turn the selector magnet and the reed magnet 62. The reed I12 is released from position I 12a to vibrate in its natural period to position I 12b and back to I12a in six half cycles of vibration thus permitting the progression of the escapement shaft I65, distributor arms 50 and 5B, and the shuttle selector rotor I90 in siX successive steps as determined by the action of the reed-driven escapement yoke I upon the escapement pins I14a, I141), I140, I14d, I14e and H4 In this process the distributor arm 50' of the transmitting distributor consecutively conmeets the transmitting contacts to line and transmits the code signals I, 2, 4, 5 marking and 3 spacing, the local and distant line relay operating accordingly. At the distant station the start-stop contact combination 22-23 remains closed with the distributor at that station shorted out of the line circuit by wire II. The line signal performance is transferred by the line relay contacts to actuate the selecting magnet 65 in the local circuit at each station, which in the rotation of the shuttle selector rotor I90 in six successive steps, sets the selecting shuttles [9011, I901), I900, I90d, and I9Ilc in the coded marking-spacing positions.

In the fifth progressive step of rotation of the escapement shaft I65, the reed start-stop magnet 65 is energized locally at each station through distributor segment 60a in readiness to catch the reed I12 upon return to position I120 in the sixth or last half cycle of vibration. The escapement shaft I65 in the sixth progressive step of rotation presents cam I81 to operate the clutch lever I31 permitting the engagement of clutch member I3I to the drive of clutch member I32 and hence the gang cam group will rotate one full revolution. The escapement shaft I65 is stopped at pin I14a, the initial or starting position, and the shut- -tle selector rotor I90 stops also at the starting position. The transmitting contact release-restore bar 256 is restored, by the cam and lever mechanism at the extremity of shaft I65, thus opening all transmitting contacts, closing the start-stop contacts, and restoring the keyboard to normal. The start-stop magnet 62 is also returned to the control of the line relay through distributor segment 60, the magnet remaining energized holding the reed because the line circuit is now closed at contacts 22-23.

As stated above the gang cam group I30 now performs one full revolution. In this revolution the five cams, 23I ribbon feed, I29 selector transfer, 230 print and space, 320 functional performance, and 229 functionals selector reset, operate upon the respective cam levers in the relationship shown in Fig. 11, see also Fig. 3. During the first 45 degrees of revolution of the cams the selector transfer is operated, the function cam 320 falls off from previous operation, and the functionals selector reset cam 229 operates to restore any function selectors that may have operated previously. The selector transfer cam I29 elevates cam lever and rod I89 to pivot the transfer yoke I93 about I9I and depress the transfer frame I92. This action resets the last selected stunt bar 2 of the translator 2I3 to normal by means of the reset disk on the transfer frame; and presents the transfer cams I92a, I92b, I92c, I92d and l92e to receive the selection established by the shuttle selectors I90a, I90b, I900, I90d and I90e, the movement of the transfer cams acting, through the push-pull bars 2I6a, 2I6b, 2I8c, 2I6d and 2I6e to start the rotation of the code disks 2I5 into the selected marking-spacing positions. See also Fig. 2. The selector transfer cam I29 in fall off permits the return to normal of the cam lever and rod I33 under spring action, (similar to the spring shown in Fig. 10) and hence returns the transfer frame I92 to normal. This action completes the rotation of the code disks into the selected marking-spacing positions, and releases all stunt bars 2I4 for one to fall into an alignment of slots in the code bars, which, in our assumption is the figures shift stunt bar 2 I 411 in Figs. '1 and 8. Between stunt bar reset and stunt bar select the type wheel I52 rotates the angular distance between the pertinent stunt bars and hence now stops in the position with stop member 2I2 against stunt bar 2I4d. Incidentally, at this stop position of the type wheel, the type bar presented to the subsequent printing action is blank and will cause no impression on the paper. The same is true for the positions at stunt bars 2I4a, 2I4b and 2I4c; i. e., selection positions for line feed, carriage return, and letters shift.

The figures shift stunt bar 2 I 4dis shown in normal position in Fig. 8. This stunt bar is drawn into the alignment of slots in the code disk translator by an individual spring about pivot 2I8. The stunt bar in movement trips the trigger latch 219 from beneath the extension pin or lug of the action bar 283 permitting this bar to snap down, under spring action on the figures shift selector 3I1 through the connecting link 29I which is pivoted at 281. See Figures 3 and '1 which show the operated positions of the details. The functional translator universal bar 293, upon being cleared by cam 229 after 180 degrees of rotation (Fig. 11), is thrown off normal which rotates the carriage spacing lock out lever 295 to interfere with the subsequent action of the carriage spacing lever 234. The figures shift selector 3I1 in movement to the left rotates the shift lever 300 about pivot 300a to thrust the yoke 305 into the position shown in Fig. 9, presenting the extension on leg 308 beneath thrust lever 304. Upon the rotation of the functionals cam 320 to 2'10 degrees this cam in the final 90 degree rotation transmits motor power to elevate cam lever 291 and depress the thrust lever 304 to rotate the shift frame 3 about pivot 305 and set the carriage into the figures printing position with respect to type wheel as shown in Fig. 9. See also Fig. 3.

Upon the completion of 360 degrees of rotation of the gang cam group, clutch I3I is disengaged from the drive of clutch I3I by the clutch lever, and cam I31 and the printing and spacing cam 230 operates to deliver a printing stroke to print hammer IiiLI; but as stated above the type wheel is blank in the figures shift position and no impression is caused on the paper. Also the spacing lever does not function being held out by lock out arm 295.

The restoration to normal of the figures shift selector 3I1 occurs in the next revolution of the gang cam group, through 45 degrees rotation of cam 229 operating upon the universal bar 294, which action also clears the spacing lockout. The figures shift frame 3I l, carriage 239 and associated details including shift lever 300 remain in the figure shift position for pertinent printing until the letters shift selector 3I8 is operated as a result of selection.

It will be apparent to those skilled in the art that the invention presents numerous possibilities for extensions and adaptations well within its scope; as for example, the utilization of the same mechanism which looks out the carriage step forward devices upon a function selection to also look out the print hammer from performing the print stroke; and the utilization of the functional translator selecting members to operate electrical contacts in a motor start-stop circuit.
